To remove HermesLookup and the other malware might require the help of a real anti-malware application. You will also need to review some system settings to make sure that HermesLookup won’t cause any more issues.

HermesLookup often comes with some fake antivirus and optimizer apps, such as MacShiny or ManClean360. These scareware apps then scan your Mac and find a ton of problems with it, but then require you to buy the premium versions of these apps to remove the “problems”.
HermesLookup gets installed at the same time and it causes some different issues:
- Online apps (email, app store, iTunes) and some websites might fail to open. In fact, your internet connection might be slow or even drop sometimes. If this happens, then HermesLookup must have messed with your network settings. Instructions fox fixing this are in the next section.
- Your browser might freeze if you use it for a long time. It might not recover until you reboot your Mac.
- The browser’s new tab and search settings are changed by HermesLookup.
- Redirects and pop-up ads appear on your screen. HermesLookup has access to all of the websites that you visit, it can inject ads.
- System pop-ups ask you to give HermesLookup access to your traffic.
HermesLookup has two goals: to stay installed for as long as possible and to manipulate your browser to show you more advertisements.
How to remove HermesLookup
It might not just be HermesLookup that you need to remove, but other hijackers, as well as some dubious Mac optimizers or fake antivirus apps. The way that HermesLookup spreads online can result in multiple infections at once.
In addition, you might need to boot your Mac in safe mode, which blocks some third-party apps from running. You can enter safe mode by holding down the Shift button on your keyboard while booting your Mac. You’ll know it worked when the words “Safe Boot” appear on your screen.
Manually delete suspicious files
If you wish to remove HermesLookup manually, then you should open the Finder app and navigate to these folders:
- /Library/Application Support
- ~/Library/Application Support
You can reach them by using the Go to Folder window found in Finder’s Go menu. Then, look for files with “HermesLookup” in their names and delete them. Additionally, look for other suspicious files that your anti-malware program might have flagged, such as CapitalCharacterSearch, UniversalWebResults, and others.
Remove the HermesLookup app (drag it to Trash) and browser extension (instructions below), as well as other suspicious apps.
HermesLookup creates configuration profiles for controlling some of your Mac’s settings. These can be found in System Preferences -> Profiles. Select and remove the HermesLookup profiles by pressing the minus ‘-‘ button.
Also, in System Preferences -> Users & Groups -> Login Items, look for programs and files that you did not add and that you don’t want to be opened whenever you start your Mac. Select and remove them.
If you are having issues with websites and online apps, then an incorrect proxy might have been set on your Mac by HermesLookup. Go to System Preferences -> Network -> Advanced -> Proxies and deselect SOCKS if it is selected. Then click Apply.
If you fixed these settings without removing HermesLookup first, then they could revert the next time you turn on your Mac. It would be a sign that the infection hasn’t been completely removed yet.
